But certain problems have to be dealt with caution, because restriction-free admission to colleges could, given the current lack of supervision and restraint mechanism, breed corruption. Media reports have exposed the misdeeds of Cai Rongsheng, former head of the student enrollment and employment division of Renmin University of China. Cai was detained in Shenzhen, Guangdong province, while he was trying to flee to Canada with a forged passport and was reportedly found to be part of a corruption scandal involving hundreds of millions of yuan.

To prevent corruption, therefore, a professional enrollment committee needs to be established in colleges offering restriction-free admission. The existing administration-led enrollment system has to be changed, because one person cannot be in charge of admissions. Also, a more sound supervision and complaint-lodging mechanism has to be established; it should be open to social supervision and transparent on admission information. More importantly, a modern university system must be developed to restrict universities' administrative powers, make the admission process autonomous and guarantee academic independence.

It is understandable that people are worried that combining the humanities and science streams in gaokao could increase the already heavy burden on high-school students. But people should know that the combination, by exposing students to the two streams, is perhaps the best way to ensure their all-round development. Before jumping to hasty conclusions on the proposed reform, people should see objectively the problem of heavy homework load that high-school students have to bear.

The gaokao-centered outlook of students and parents has become a chronic disease. Some schools have changed their teaching schedules to help students excel in gaokao. The result in most cases has been repetitive exercises. Already heavily burdened final-year high-school students spend a lot of time on meaningless rote learning and mechanical drills. At best, they can be called "exam machines". That's why the reform aims at reducing the burden of homework for students.

If schools offer a scientific range of subjects, properly arrange the teaching schedule and cancel classes for mechanical learning, it would reduce students' burden and give them more free time to pursue the subjects they are genuinely interested in and develop their personality, which would ultimately help improve their knowledge structure and improve their overall academic and individual quality. All these require a change in people's mindset. As a beginning, we could include some other factors, along with gaokao scores, to gauge the true potential of a student seeking admission to a college.
